A pressure on the abdomen by pneumatic cuff was performed in 13 decerebrated vagotomized cats for enhancing the excitatory intercostal-to-phrenic reflex. "Moving averages" of the electrograms of the phrenic nerve and oblique abdominal muscles, as well as abdominal cavity pressure were recorded. In these conditions the changes of the phrenic activity were weak and inconsistent. Significant changes of the peak amplitude of phrenic ENG were absent. In the majority of the experiments diminutions of the respiratory cycles, inspiratory and expiratory durations (up to 6%), as well as enhancing of the rate of rise of phrenic activity (up to 5-7%) took place. The latter can be a manifestation of the intercostal-to-phrenic reflex. This reflex in breathing may have but a weak influence on the phrenic motoneurons excitation.
对13只去大脑迷走神经切断的猫施加气动袖带对腹部的压力，以增强肋间到膈神经的兴奋性反射。记录膈神经和腹斜肌的电图“移动平均值”以及腹腔压力。在这些条件下，膈神经活动的变化微弱且不一致。膈神经ENG的峰值幅度没有显著变化。在大多数实验中，呼吸周期、吸气和呼气持续时间缩短（高达6%），以及膈神经活动的上升速率增加（高达5 - 7%）。后者可能是肋间到膈神经反射的表现。这种呼吸反射对膈运动神经元的兴奋可能只有微弱的影响。
